If it rains particularly hard in the Sumatran rain forest, the already arid region of East Africa is onset with drought. Researchers from the Biodiversity and Climate Research Centre (BiK-F), the California Institute of Technology, the Univerity of Southern California and the University of Bremen found that this cyclic, bipolar climate phenomenon has likely been around for 10,000 years. The pilot study, published today in, Proceedings of the National Academy of Sciences, sheds light on the climate system of a region whose rainfall patterns have a major impact on global climate. Therefore, this study is of special interest to climate researchers.http://phys.org/news/2014-06-hidden-history-waxes-reveal-rainfall.html

Environment Thu, 05 Sep 2013 11:30:24 EDTnews297599411The long and rich life of tropical clouds: Understanding environmental conditions that help tropical clouds flourishScientists at Pacific Northwest National Laboratory uncovered another clue as to how tropical clouds live long and prosper. Moisture from the middle layer of the atmosphere, both before and after the clouds begin forming, is the determining factor for the lifetime of these cloud systems. When the researchers compared clouds of equal lifetime that initiate over land and over water, those over land were more intense than those beginning over the ocean, especially during the early stages. Contrary to previous studies, they found that wind shear-the change in wind speed and direction-has no discernible effect on the lifetime of the tropical cloud systems.http://phys.org/news/2013-09-rich-life-tropical-clouds-environmental.html
Earth Sciences Mon, 02 Sep 2013 09:28:53 EDTnews297332920Extreme weather events fuel climate changeWhen the carbon dioxide content of the atmosphere rises, the Earth not only heats up, but extreme weather events, such as lengthy droughts, heat waves, heavy rain and violent storms, may become more frequent. Whether these extreme climate events result in the release of more CO2 from terrestrial ecosystems and thus reinforce climate change has been one of the major unanswered questions in climate research. It has now been addressed by an international team of researchers working with Markus Reichstein, Director at the Max Planck Institute for Biogeochemistry in Jena. They have discovered that terrestrial ecosystems absorb approximately 11 billion tons less carbon dioxide every year as the result of the extreme climate events than they could if the events did not occur. That is equivalent to approximately a third of global CO2 emissions per year.http://phys.org/news/2013-08-extreme-weather-events-fuel-climate.html

Following 7 months of normal rainfall, the drought was one of the largest deviations from seasonal precipitation rates seen in the region since observations began in 1895. When such extreme events take place today against the backdrop of ongoing global climate change, they raise questions about the relationship between climate change and natural disasters.http://phys.org/news/2013-08-great-plains-drought-climate.html
